Application filed July 5,

To all whom it may concern:

Be it known that I, ERIK H. ALDEBORGH a subject of the King of Sweden, and resident of Poughkeepsie, in the county of Dutchess and State of New York, have invented a new and useful Improvement in Snap Gauges of which the following is a specification.

In snap gauges of the typeherein set forth where inner and outer pairs of opposed adjustable anvils are employed, the desirability for both speed and accuracy in gaging the work is important. The spaces heretofore left between the opposed anvils oi the inner pair and the opposed anvils of'the outer pair have not only been a deterrent to speed in the use ofthe gauge but also permitting the work being gaged to be scratched or otherwise marred by striking the inner edges of the exposed ends of the anvils, which anvils as is well known, are of extremely hard steel.

The object of my invention is to provide means such as filler pieces bridging the spaces between the anvils of the inner pair and the anvils of the outer pair, for facilitating the rapid gaging of the work without impairing the accuracy of the same, the work at the same time being guarded by said filler pieces from being scratched or otherwise marred by the anvils.

Practical embodiments of my invention are represented in the accompanying drawings, in which i Fig. 1 represents a face view of a snap gauge of well known and approved c0nstruction, showing one form of filler piece.

Fig. 2 represents a section taken in the planes of the line 11-11 of Fig. 1.

Figs. 3 and 4 represent detail views showing a second form of filler piece in front and edge elevation in position for use.

Figs. 5 and 6 represent similar views or a third form of filler piece.

Figs. 7 and 8 represent similar views of a fourth form of filler piece.

Figs. 9 and 10 represent similar views of a fifth form of filler piece.

Figs. 11 and 12 represent similar views of a sixth form of filler piece.

The snap gauge 1 has its branches 2 and 3 provided with inner and outer pairs or opposed adjustable anvils 4. 5 and 6, 7 respectively, the exposed ends of said anvils being beveled as is usual along their outer 1923. Serial No. 649,652.

edges to facilitate the admission of the work to be gaged. I I

The filler piece illustrated in Figs. 1 and 2 has a thicker intermediate portion 8 and thinner inner and outer end portions 9 and 10. The filler piece is split longitudinally as shown at 11 toform two branches having corresponding semi-circular recesses 12 and 13 for receiving the exposed end of one of the inner anvils. A screw 14: extends transversely through the branches of the filler piece at the thicker intermediate portion 8 for clamping the filler piece to the inner anvil 4 or 5, as the case may be. The outer end of the tiller piece is provided with a semi-circular recess 15 for receiving a portion of the outer anvil 6 or 7, as the case may be.

From the above description it will be seen that the filler piece is adjustable with the inner anvil while the outer anvil is adjustable independently of the filler piece.

In the form shown in Figs. 3 and 1, the filler piece 16 has no thicker intermediate portion but is of the same thickness throughout and the clamp screw 17 passes through the branches inside the inner anvil.

In the form shown in Figs. 5 and 6 the filler piece 18 is of the same thickness throughout but the clamp screw 19 passes through the branches 20 and 21 between the inner and outer anvils, the filler piece in this instance being divided as shown at 22 from the outer semi-circular recess 23 to the inner circular recess 24:.

The formshown in Figs. 7 and 8 is quite similarto the form shown in Figs. '5 and 6 except that the tiller piece is provided with a thicker portion 25 intermediate the thinner inner and outer end portions 26, 27, permitting the use of a larger screw than that shown in Figs. 3, 4t and 5, 6.

The form shown in Figs. 9 and 10 is quite similar to the form shown in Figs. and 4: except that the filler piece is thicker at its inner end as shown at 29, to permit larger clamp screw to be used.

The form shown in Figs. 11 and is one adapted for anvils having enlarged heads. In. this form the filler piece is completely divided into two half members 31. 32. connected by thin webs 33. 34. for embracing the inner anvil back of the head. Two clamp. screws 35. 36 are shown for clamping the half members of the tiller pieces to, the anvil,

In all of the forms herein shown and described, the filler pieces are substantially flush with the exposed ends of the outer anvils so that there is no danger of the work being marred when Withdrawn from the gauge. Furthermore these filler pieces serve as guides for directing the work past the outer anvils to the inner anvils, thereby permitting a much more rapid manipulation of the gauge than heretofore.

In practice the surfaces of the filler pieces should be slightly below the gagingsurfaces of the aanvils' for-clearance. Under ordinary conditions the clearance should be from 2002 to .005.

It is evident that various changes-may be resorted to 1111116 form, construction and arrangement of the several parts without departing from the spirit and scope of my posed faces of the filler pieces andthe exposed'ends of-the inner anvils beyond said faces.

In testimony, that I claimthe foregoing as my invention, I have signed my name this 15th day of*May, 1928.
